458 GEARBOX ISSUES?

nope

 

This is not accurate. The gearbox issues affect ALL model years.

There is a 2014 458 at my dealer right now with the gearbox failure. Last month they did a 2015 458.

Model year has nothing to do with this issue.

 

Ferrari replaced my g/box rather than rebuild/repair; I don’t know why some are repaired, some rebuilt; I’m sure there must be a good reason though. Dealership told me was not model year specific.

Thank you. Our local dealer Ferrari mechanic sent me this pic. It’s a 2013 or a 2014 458 gearbox being repaired. Forgot which one he told me

I posted separately my DCT and gear oil analysis. Both look great for a car that’s tracked, but these results won’t predict sensor failure if that’s the predominant issue, which appears to be the case.

 

Gearbox in my 2011 Italia wouldn’t go into park. Began getting gearbox not in parking position and key wouldn’t release without pressing key release button near the ignition
Also had to manually put car into park or it stayed in neutral
Car started going into neutral by itself soon after after very low speeds

1. Diagnosed as bad sensors (all of them) by 1 dealership in NorCal who shall remain nameless. A $27k repair estimate

Trailered car to second NorCal dealership for second opinion

2. Diagnosed as total gearbox failure, internal gearbox park lock was sheared and another gear was poached. Gearbox itself could not go into park.
A $50k getrag replacement estimate. In fairness they got the diagnosis correct but they didn’t want
To entertain fixing it. Would only do a total replacement

3. Trailered car to San Raphael Motorsports who happened to have a couple spare salvage getrags for parts. The specific parts mine needed to be rebuilt.
It also needed a pressure solenoid.
A $25K repair and a good as new getrag that shifts like butter. Also did the open flash tune which
really maximized the S-LINE exhaust and fabspeed headers I had on the car. Car belches, shifts
faster, goes faster and just feels smoother all the way around. I’m a believer in openflash


is there a moral to the story? Well,.. patience is a virtue with 458 getrags?
Sometimes the dealer is wrong in their diagnosis, get a second option on if you can?
There are some phenomenal garages out there like San Rafael Motorsports and I’m lucky to have
them in my life?

Take your pick.

 

I have this question too. just like LASIK surgery, those who had failed or not satisfied, will rage in the internet forums. sure there are thousands of un happy lasik patients with botched results. but how many is the total patients who had it done and did not complaint ?
in this case, how many 458/calis that built in 2010-2014 and happy and never had DCT/gearbox problems ? if failure rate is still considered minimal compare to happy user rate, then we shouldnt be worry too much. just take good care of her like nuno said

 

I have a similar issue

Went out for a drive this morning, used race mode for a bit (5 minutes) and when I tried to park the car after getting home, R would not engage ... holding down the R button would lead to the "Gearbox failure" light on the dash to illuminate but the light would extinguish as soon as I let go of the R button.

Drove around slowly for 10-15 minutes in sport mode and tried to engage R again and it sometimes selects. Can't tell what's causing it, finally got the car back in my spot after sitting in the lot like an idiot in neutral for 10 minutes.

Will take it to my specialist later this month and ask what he thinks.

 

Will try this

 

Had this very same thing happen several years ago on my 2012 458. Worked fine in sport mode but if I switched to race, no go in reverse.

Dealer claimed it was the R button! Why that would matter is beyond me. Should be a single-pole single-throw kinda switch. Everything else is software. They claimed to have replaced switch and all worked fine. SMH.

Did switching back to sport mode immediately give you reverse back ? or was it fked forever from that point ?

 

Only in sport or wet mode. Moving it back to race mode defeated reverse!

I'm in a slightly different situation

I can get reverse while in race mode, but reverse only engages like 10% of the time ...

Don't know how much more trouble shooting I want to go and do on my own, might just wait to take it in to the mechanic's

 

When being denied Reverse, what does your brake pedal feel like? Do you get an error message reminding to depress the brake pedal?

If so then the problem may not be the DCT , but rather the brake booster, check valve , insufficient vacuum.
There is a DCT limp home mode where you only get only even or odd gears. If that is the case, then you will need the DCT worked out

 

No brake pedal warning, no vibration or anything from the brake pedal
I have full access to all forward gears (for now)

 

Makes me think it’s the button itself.

 

I sure hope so

 

If you want to DIY, buy a replacement button and swap it out

 

Hello, what did you end up doing? Great suggestion by Malibu guy.

I think this poster also has a leak in the output shaft.
So it may be abnormal pressure levels in the DCT which can be causing the system to deny Reverse
Let him fix his leak first and then see if Reverse is possible
I think bring the car to a dealer to run DCT diagnostics would be a good move. These DCTs are complicated

 

I'm on vacation at the moment, will take the car to my independent for a code read to see if it helps shed some light on the issue this weekend

 

I don't think I have any leaks (that I know of) but will get a bettee picture this weekend when I take it to my independent

 

For diagnostics, is the dealer who has the authorized and proper computers so much more to pay ?
How do you know your independent has the correct computers to check the DCT?
Ferrari guards and does share the intellectual property
Saving money isn’t always as simple as one thinks in the beginning

 

Might do both?

The shop works on paganis so it can't be THAT bad...
